<strong>CH</strong>-<strong>TRAMPAC</strong> Document Rev. 2, May 2005methodology described in Section 5.2.3 (for analytical category waste) or fromSection 5.2.5 (for test category waste). Mixing <strong>of</strong> shipping categories and payloads <strong>of</strong>any authorized contents, including credit for dunnage, is allowed as described inSection 6.2.4. If mixing shipping categories pursuant to Section 6.2.4, indicate that thehydrogen/ flammable gas generation rate limit for the payload is not applicable (e.g.,“NA – Mixing”).• Type <strong>of</strong> Payload (Section 2.1): The payload configuration shall consist <strong>of</strong> an approvedtype <strong>of</strong> payload container. If the payload type is “Standard Pipe Overpacks,” each sevenpackin the payload must be comprised <strong>of</strong> only 6-in. standard pipe overpacks or 12-in.standard pipe overpacks.• Transportation Packaging: The type <strong>of</strong> packaging used (TRUPACT-II or HalfPACT)shall be recorded• Date ICV Closed: The date that the ICV is closed shall be recorded.• Time ICV Closed: For payloads designated for controlled shipment only, the time thatthe ICV is closed shall be recorded. For other payloads, the time that the ICV is closedneed not be recorded.Bottom Payload Assembly Composition and Top Payload Assembly CompositionThe following data shall be recorded from each PCTCD (Table 6.2-1 and Table 6.2-2) or fromthe OPCTCD (Table 6.2-3), as applicable, for each payload container comprising the payload:• Payload container ID number or “DUNNAGE” or “EMPTY” (Section 2.4)• Measured weight and measurement error (Section 2.3)• Measured decay heat and measurement error (one standard deviation) (Section 5.2.3)• Measured fissile mass and two times the measurement error (two standard deviations orone times the RSS error if values are taken from an OPCTCD) (Section 3.1)If the data are obtained from the OPCTCD, errors should be the calculated RSS errors (thesquare root <strong>of</strong> the sum <strong>of</strong> the squares <strong>of</strong> the individually listed errors).In addition, record the measured hydrogen/flammable gas generation rate for payloadscontaining test category waste from each PCTCD (Section 5.2.5). If mixing shipping categoriespursuant to Section 6.2.4, calculate and record the hydrogen/flammable gas generation rate andthe FI for each payload container. If the payload assembly consists <strong>of</strong> overpackedconfigurations, indicate that the hydrogen/flammable gas generation rate and FI are notapplicable (e.g., “NA – Mixing”) and record the hydrogen/flammable gas generation rate and FIfor each overpacked container on the appropriate OPCTCD (Table 6.2-3). This calculation istypically performed using a verified/validated s<strong>of</strong>tware package.Payload Totals• Weight <strong>of</strong> Pallets, Reinforcing Plates, Slip Sheets, Guide Tubes, Adjustable Slings, etc.(Section 2.3): The total measured weight <strong>of</strong> the pallets, reinforcing plates, slip sheets,guide tubes, etc., for TRUPACT-II or HalfPACT payloads is recorded. If the weight isdetermined through a single measurement <strong>of</strong> the payload assembly, indicate the weight <strong>of</strong>the pallets, etc., is not applicable (e.g., “NA”).6.2-21
